DASH diet, short for Dietary Approaches to Stop Hypertension, is one of the tools that you can use to manage your blood pressure. It is a lifelong way of eating designed to control or prevent high blood pressure. It requires you to cut back on foods that are high in cholesterol, trans-fat, and saturated fat, salt, sweets, red meats, and sugary drinks. You will eat more fruits, vegetables, whole-grain foods, nuts, poultry, legumes, and low-fat dairy.
